To all whom may concern. I

- Be it known that I, ROBERT A. Jniaciins,

ofthecity-and county of Providence and State of Rhode 'Island,'have invented-cervtain new. and useful Supports for Pi e- Hangers; and -I do hereby declare the 01- lowing specification, taken in connection with. the accompanying drawmgs, formmg a part of the same, to be a full, clear, and

exact description thereof.

In the construction of modern buildings the floors and walls are frequently made of concrete, cement, or the like, built or formed.

' upon false =wood work,'whicl1 false wood work, when'the concrete or similar material is set, is removed. The plaster is applieddire'ctly to the concrete or similar material;

My invention relates to a support or anchor for pipe hangers which are particularly adapted for use in floors and walls constructed in the above manner. Heretofore the practice has been to drilla'hole in the solid concrete and insert anexpansion bolt, which expansion bolt is provided with suitable means for securing the pipe hanger thereto. Such -method is 'diflicult and expensive, requiring much labor, and the cost of the expansion bolts employed is considerable; I

The object o f my invention is "to provide a suitable support which will overcome the Fig. 2 is a corresponding view 'after the concrete has been applied. Fig. 3 is acorre objections to the supports heretofore used, and which" will also furnish a more. rigid and satisfactory support for the pipes to be suspended therefrom.

To that end the invention consists anchor or support adapted to be placed in position before the concrete or cement is applied, and so' as to be embedded: and heldin the concrete or cement when the same becomes set.

Referrin to the drawings, Figure" I isv a side elevation of my improved support'or anchor supported in the. false wood work prior to the application of the concrete.

spondin view showing the false wood work remove Fig. 4 is a sectional View on the line :r'm, Fig. 6. Fig. 5 is a sectional .view on the line yy, Fig. 6. Fig. 6 is a side elevation of my improved support or anchor amount of metal may of an] showing the ceiling completewith'the plaster supplied and the pipe-hanger in place in said support.

The anchor or socket which may be cast comprises a body portion 1 and ,a projecting or otherwise formed .of any suitable metal,

portion or neck 2. The body portion is provided with a flanged head 3 which serves to support the anchor when embedded in the concrete against downward pull. Preferably the neck portion 2 is of somewhat reduced diameter so as to form another flange tion, and so as toform the-webs or ribs 5.

as shownin the.drawings and particularly in cross section in Fi 4, as thereby the e considerablylessened and at the same time pockets or recesses will be formed into which the concrete or cement can enter and so that the sup ort or" anchor-will be more firmly and secure y held in place in the concrete, -With this web construction also the webs or ribs 5 serve to prevent the support or anchor from turning,

as for instance when the pipe-hanger is being screwed; therein. If desired the body portion 1 may be cylindrical in shape, but

it preferred to make the same tapering or of frusto-conical shape, as shown, as this construction serves to still further hold the support or anchor against downward pull.

The projecting neck portion 2'is tapped 1 witha screw thread, so that the end of the pipe-hanger 6 may bescrewed therein.

The'manner of applyin the support or anchor is as follows: A ho e isbored in the false wood work 7, and the neck 2 of the support is inserted in this hole, and so that the support or. anchor will be properly located and-held in position for the application of the concrete, as shown in Fig. l.

"Fi 2 shows the concrete 8 applied upon the also wood work withthe' anchor embedded therein andfwith the false wood work still in position fAfter the concrete or cement has become hardened and set the false wood work is removed, leaving the neck portion 2 of the anchor projecting applied, said neck portion will project somewhat below the lower surface of the plaster, as shown in Fig. 6, as such construction will guard against the liability of the neck portion being buried in or covered by theplaster and against the liability ofv the hole tapped-therein for the reception of the hanger rod being filled with plaster. It will be evident, however, that said neck portion 2 need. only be of sufficient length to properly support the anchorin the false work while the concrete is being applied. It is also evident that if said neck portion were not of sufficient length to project below the plaster, the liability of said neck portion being covered by or the holetherein filled with plaster can be prevented by simply inserting the hanger rod in place in said neck portion before the plaster is applied.

In order to support the anchor in proper vertical position while the concrete is being applied it is desirable that the neck portion 2 should fit the hole formed for its reception in the false wood work comparatively snug. It has been found that under the action of the moisture in the concrete there was a liability of the wood work swelling and gripping ttlllS neck portion to such an extent as to make it difficult to remove the false wood work. To guard against this difiiculty the neck portion-2 is preferably provided with projecting ribs 10. With this construction the wood work will be in contact only with the comparatively narrow outer surfaces of these projections, and the effect of the gripping action will be correspondingly reduced, and so that the wood work may be readily removed, even if swollen by the moisture.

By the use of an anchor or socket like that above described, a pipe hanger support is provided which may be conveniently secured in position and at comparatively little expense, while at the same time the device furnishes a firm and rigid su port for the'pipe-hangerand the pipe carrie thereby.

What I claim as my invention and desire to secure by Letters Patent is:

1. An anchor or support adapted to be embedded in plastic material comprising a body-portion and a neck-portion, said neckportion being provided with spacing ribs or projections, substantially as described.

2. An anchor or support adapted to be embedded in plastic material comprising a body-portion provided with flanges with intermediate webs or ribs connecting said flanges, and a neck-portion provided with spacing ribs or projections, substantially as described.

3. An anchor or support adapted to be embedded in plastic material comprising a frusto-conical body-portion provided with flanges and with'intermediate webs or ribs connecting said flanges, and a neck portion provided with spacing ribs or projections, substantially as descrlhed.
